| Abstract: | The optimum iodide concentration (excess) for the extraction of bismuth as Bil3 into isoamyl acetate from 1—5 N sulfuric acid solution is approximately 5.10-3M. At this iodine concentration the extraction coefficient Bi] isoamyl acetate/Bi]H2O is approximately 130 (25-30°) when the ratio of isoamyl acetate to aqueous phase is 1 : 4. Mixturcs of isoamyl acetate and isoamyl alcohol in the proper ratios extract Bil3 to a greater extent than either solvent alone. |
